Rare Supernova Explosion



Core-collapse supernova explosion expelling nearly spherical debris shell.

This is the first time astronomers have found a supernova explosion with properties similiar to a gamma-ray burst, but without seeing any gamma rays from it. Scientists expect the discovery--made using the National Science Foundation's Very Large Array (VLA) radio telescope--will point the way toward locating many more examples of these mysterious explosions. Radio observations will be a more powerful tool for discovering these kind of supernova in the universe than gamma-ray satellites.

To learn more about the discovery, see the NRAO news story "Astronomers Find Rare Beast by New Means." >>  http://www.nrao.edu/pr/2010/enginesn/  (Date of Image: 2009) [Image 1 of 2 related images. See Image 2. >> http://www.nsf.gov/news/mmg/mmg_disp.cfm?med_id=69053&from=mmg ]
